v3.2.0

Add ability to override the way how event class is resolved from event type.

Previously the event was resolved from an event type only in the pre-defined way - Object.const_get(event_type). Current release adds an ability to add your own resolver using config.event_class_resolver config option. You should define a Proc that accepts a string and returns a class. Example:

EventStoreClient.configure do |config|
  config.event_class_resolver = proc { |event_type| event_type == 'some-event' ? SomeEvent : AnotherEvent }
end

If config.event_class_resolver returns nil - config.default_event_class class will be picked.
